Abstract
The techniques that can be used to enhance biological degradation in landfills
include: leachate recirculation, addition of nutrients, shredding, sludge and buffer
solutions addition, lift design, temperature and moisture content management.
Manipulation of these variables promotes a more conducive environment for
microbial activity. This paper presents the results of a leachate recirculation
experiment into three solid waste cells. The leachate was recirculated over a period
of 65 weeks, and effluent samples were obtained on a weekly basis and analyzed for
pH, BOD, and COD concentrations. The experimental results indicated that addition
of supplemental materials to leachate during recirculati
